Unidoom DM X

Unidoom DM X (more popularly known as just UDMX) is a Doom II deathmatch mapset created by the Unidoom multiplayer clan and mapping group. It was released on December 25, 2004. It is the fourth and final entry in the widely celebrated Unidoom DM series. After undergoing several years of sporadic and aimless work followed by an entire year devoted to its renewal and completion, the fourth installment of the series was released on December 31, 2008, four years after the release of the previous entry, Unidoom DM 3. Matt Cibulas (RottKing) served as the project leader for this instalment.

UDMX is the first entry in the series to fully replace Doom II's original 32 levels, several of which are replaced by remakes ("flashbacks" as called throughout the WAD) of maps found in UDMX's predecessors. Unlike UDM3, the WAD uses a rich variety of custom textures and boasts a new palette that saturates reds and greens and deepens blues. While under development, the project underwent a series of name changes: initially called what it is now, it was eventually renamed "UDML" (Unidoom DM Legends), then briefly "UDMC" (Unidoom DM Classic), and lastly UDM4; however, it was soon decided that it would return to its original title. UDMX celebrates Unidoom's 10th anniversary, bearing the "X" in its name to represent the ten years that had passed since the original 1998 founding of Unidoom at the time of the WAD's release. At a whopping 20.7 megabytes, UDMX is the largest UDM installment by file size. UDMX has received much critical acclaim throughout the community, deemed by reviewers as one of the greatest deathmatch megawads to have ever been made. UDMX was named the Best Multiplayer WAD at the 15th Annual Cacowards.

A trailer for it was released on March 23, 2008. A follow-up trailer showcasing newer maps was released on August 28, 2008.
